The United States Military Government of the Philippine Islands (Spanish: Gobierno militar estadounidense de las Islas Filipinas; Tagalog: Pamahalaang Militar ng Estados Unidos sa Kapuluang Pilipinas) was a military government in the Philippines established by the United States on August 14, 1898, a day after the capture of Manila, with General Wesley Merritt acting as military governor. During military rule (1898–1902), the U.S. military commander governed the Philippines under the authority of the U.S. president as Commander-in-Chief of the United States Armed Forces. After the appointment of a civil Governor-General, the procedure developed that as parts of the country were pacified and placed firmly under American control, responsibility for the area would be passed to the civilian.
General Merritt was succeeded by General Elwell S. Otis as military governor, who in turn was succeeded by General Arthur MacArthur. Major General Adna Chaffee was the final military governor. The position of military governor was abolished in July 1902, after which the civilian office Governor-General became the sole executive authority in the Philippines.
Under the military government, initially with soldiers as teachers; civil and criminal courts were reestablished, including a supreme court; and local governments were established in towns and provinces. The first local election was conducted by General Harold W. Lawton on May 7, 1899, in Baliuag, Bulacan.
Capture of Manila
By June, U.S. and Filipino forces had taken control of most of the islands, except for the walled city of Intramuros. Admiral Dewey and General Merritt were able to work out a bloodless solution with acting Governor-General Fermín Jáudenes. The negotiating parties made a secret agreement to stage a mock battle in which the Spanish forces would be defeated by the American forces, but the Filipino forces would not be allowed to enter the city. This plan minimized the risk of unnecessary casualties on all sides, while the Spanish would also avoid the shame of possibly having to surrender Intramuros to the Filipino forces. On the eve of the mock battle, General Anderson telegraphed Aguinaldo, "Do not let your troops enter Manila without the permission of the American commander. On this side of the Pasig River you will be under fire."
On August 13, with American commanders unaware that a ceasefire had already been signed between Spain and the U.S. on the previous day, American forces captured the city of Manila from the Spanish in the Battle of Manila. The battle started when Dewey's ships bombarded Fort San Antonio Abad, a decrepit structure on the southern outskirts of Manila, and the virtually impregnable walls of Intramuros. In accordance with the plan, the Spanish forces withdrew while U.S. forces advanced. Once a sufficient show of battle had been made, Dewey hoisted the signal "D.W.H.B." (meaning "Do you surrender?), whereupon the Spanish hoisted a white flag and Manila was formally surrendered to U.S. forces. This battle marked the end of Filipino-American collaboration, as the American action of preventing Filipino forces from entering the captured city of Manila was deeply resented by the Filipinos. This later led to the Philippine–American War (1899–1902), which would prove to be more deadly and costly than the Spanish–American War (1898).
